Safeguarding Groundwater Realtime Environmental Monitoring and Groundwater Protection Real-time analytics, data and sampling from the vadose zone for data driven decisions. Water resource protection | Agritech | Dam safety | Mining & tailing dams | Remediation | PFAS Sensoil's Vadose-zone Monitoring System: Real-time sensing of the unsaturated domain. Real-time monitoring of the unsaturated zone is key for groundwater protection against pollution hazards. Sensoil's patented Vadose-zone Monitoring System (VMS) is designed to provide continuous real-time information on the hydraulic and chemical properties of percolating water in deep vadose zone through in-situ measurements of natural undisturbed conditions. Minimization of subsurface pollution and optimization of remediation efficiency depend on reliable and effective monitoring tools that provide real-time information on the chemical and hydrological state of the percolating water. Sensoil's VMS system is already installed in global locations on 5 continents.
